hi,
i am a bit new to this multiICE environment.i have the insight5.0 debugger and the cross-compiler for ARM7.i want to understand how to go about using the multiICE with JTAG.(i understand that it needs some RDI calls).
i think i need to say
(gdb) target rdi <my parallel device>
but what will be the name of the parallel device(a file??)
can i use the same multiICE as an embeddedICE as it is backward compatible(and if gdb doesnt support multiICE as yet).
all inputs will be greatly appreciated.
thanks a lot.
regards
rajeev

The RDI stuff in gdb uses either TCP, serial port,
serial/parallel combination. I don't believe it's possible to
use just the parallel port, since the RDI stuff in gdb only
uses the parallel port to write stuff to the JTAG box.

That depends on your OS installation. Under Linux it's
typically /dev/lp0 or /dev/lp1

I don't understant that question.
If you can, try to get it working with just a serial connection
at 9600 baud. Once you get that working, you can add the
parallel port connection to speed up downloads.

All,
According to the eCOS web page at
http://sources.redhat.com/ecos/tools/win-thumb-elf.html
the current 2.95.2 does not support arm thumb, what is the issue? And when
might this be fixed?
Tim

The issue isn't that 2.95.2 doesn't support arm-thumb, the issue is that it
won't successfully compile eCos in thumb mode.
There doesn't seem to be a complete solution to that problem at the moment.
What I have done is to use a recent CVS snapshot of the gcc sources,
compiled for arm-elf. (Newer versions of gcc support -mthumb to generate
Thumb code). It still is not possible to compile eCos as Thumb code (known
gcc bug). However you can compile eCos in ARM mode, and specify the
-mthumb-interwork switch. You can then compile your app in thumb mode with
-mthumb -mthumb-interwork).
Note that in order to achieve this, you will also need to have the standard
libraries built with thumb interworking enabled. Jonathan Larmour posted
instructions for this a couple of weeks back, check the list archives.

there's this section in the ecos manual:
http://sources.redhat.com/ecos/docs-latest/tutorials/arm/ecos-tutorial.d.htm
l#pgfId=2562244
and there's also an app note from cirrus:
http://www.cirrus.com/pubs/an191-1.pdf?DocumentID=437
that both talk about multi-ice. i was unable to get things to work, though,
which might be related to the fact that i have v1.4 of multi-ice while the
cirrus note refers to v1.3. has anyone had any success?
